Abstract
Along with the development of the automotive industry,autopossession of the rapid increase of automobile, the performance requirements of enlarging, lead to the vehicle maintenance equipment demand increase gradually. In vehicle movement process, because such accidents occurred turbulence, can cause rear axle shell in half axle sleeve tube damage, develop with independent intellectual property rights of half axle sleeve tube dismantle installed also became partofChina'sautomobilemaintenance industry important topic, and to enhance our country's special machine, the design level of drive our country repair vehicles independent design development to have the important meaning. Along with the rapid development of science and technology, we must accelerate the advanced design idea, and applied to practice. Therefore, high-tech half axle sleeve pipe down as heavy vehicle repair installed an essential tool, is to have the prospects of development of special equipment repair vehicles.
In this paper, through the plenty of investigation, to modify a kind of manual operation as the foundation, pressure rated for 20WPa high-pressure maintenance equipment. This paper mainly made by hydraulic pump and hydraulic cylinder, motor, jack, body, frame, accessory device consisting of hydraulic system design. Finally, after completion of modification of half axle sleeve tube dismantle installed through the necessary control, safety and stability etc., the main vehicle performance of calculation and analysis, the calculation results show that the vehicle performance meet the requirements.
